invented certain new and useful Improvements in Gas Heaters; and I do declare the following to be a full, clear, and exact decription of the/invention, such: as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to improvements in heaters such asthose which are commonly operated by gas, and it is the object of the invention to provide a generally improved construction which will be rather' simple and inexpensive, yet will be highly efiicient' and durable.

Withtheforegoing and other objects in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure 1 is a perspective view of, a gas heater constructed in accordance with my invention. j j

Figure 2 is a vertical "transverse sectional view.

Figure 3 is a horizontal sectional view as indicated by line 3-3 of Fig. 2.

Figure 4 is a vertical longitudinal section substantially on line 4-4 of Fig. 2.

Figure 5 is a per ective view with the air heating jacket an other parts removed.

Figure 6 is a perspective view of a portion of the fire wall.

Figure 7 is a per ective view of one of the members which 0 ose the spaces between inner and outer side walls and also mask the inner surfaces of the innermost of 'said walls.

Figure 8 is a perspective view of the burner.

Figure 9 is adisassembled perspective view showing the preferred manner of constructing the front portion of the jacket to In the drawings above briefly describe the numeral 1 designates a horizontal base plate which is preferably provided with downturned flanges 2, to which appropriate legs 3 are secured. Risin from the rear edge portion of the base 1, 1s a vertical back wall 4, and extending forwardly from the vertical ends of, this back wall are two opposed sidewalls 5, said side walls being spaced inwardly from the ends of the base Canvnn 1 and being preferably provided at their lower ends with angle metal bars 6 which are secured by bolts or the like 7, to the base. The upper ends of the side walls 5 are rearwardly inclined, and a similarly inclined top 8 rests onsaid inclined ends and extends forwardly therefrom, said top preferably having downwardly bent flanges 9 riveted, bolted or otherwise secured to the outer sides of the walls 4 and 5. The base 1, back wall 4, op osed side walls 5, and top 8, co-operate in orming a burner-containing casing which is open at its front. Disposed horizontally in the lower ortion of this casing, is a burner 10 whic is preferably of quadri cylindrical form intransverse section, this burner provided with an appropriate internal gas distributor 11,v and with a gas supply pipe 12 having the usual air; mixer 13. For securing the burner in lace, I have provided it with a pair of orwardly projecting, C-shaped brackets 14 whose lower arms are secured to the base 1 by bolts or the like 15, the upper ends of thesebrackets having a function to be hereinafter described.

Y A fire wall 16 is mounted in the casing bei hind the burner 10, said fire wall consisting of a lower vertical section 17, an upper vertical section '18, and a horizontal intermediate section 19 which rearwardly offsets the section 18 from the section 17. The .7

ends of all of these sections are provided with laterally bent flanges 20 so that they are transversely stifiened against bending or warping, and at least,two of these flanges are instrumental in securing the fire wall in the casing, rivets 21 being shown, passing through the uppermost of said flanges and through the opposed side walls 5. The n per portion 0 the lower fire wall section 1 is preferably formed with a plurality of erforations 22 which lead directly over the urner 10,;and the contiguous portion of said burner is by preference provided with a multiplicity of openings 23 which pro duce substantially a solid wall of flame immediately in front of the perforations 22. Thus, all air and unburnt gases passing through these perforations must immediately come in direct contact with this sheet or wall of flame, to be immediately consumed. For

admitting air behind 4 the fire wall 16, a

ieries of openings 24 are formed the ase 1.

. An inclined bafiie plate 25 is secured in the casing, in downwardly spaced relation with the top 8 thereof, said baflle plate extending over the fire wall 16, in spaced relation with the latter, and having its rear edge portion directed downwardly as at 26, in a plane spaced rearwardly from said fire wall. The front edge of the baffle plate is rearwardly spaced from the front edge of the top 8. By this relation of parts, all unburned gases rising from the burner 10 are caught either by the top 8 or the baffle plate 25 and are by these parts directed to thespace behind the fire wall 16, so that they can with the air' from the openings 24 and pass through the perforations 22 to be consumed by the solid wall of flame. burning at the burner openings 23. Thus, the poisonous gases which would otherwise escape, are absolutely consumed "and there is no danger from using the heater even in poorly ventilated rooms.

An air heating jacket isprovided around the casing above described. This jacket includes a vertical back wall 27 which is rearwardly spaced from the rear flange 2 of the base 1. Extending forwardly from the vertical edges of this back wall27, are two opposed side walls 28 whose lower ends may well be secured against the endmost of the flanges 2, by bolts or the like 29. Between these walls 28 and the side walls 5, the base 1 is formed with air inlet openings 30. A

top is mounted on -the walls 27 and 28 and this top preferably comprises a back horizontal section 31 and a front rearwardly inclined section 32, the former having hot air escape openings33. Both sections 31 and 32 are preferably provided with nickel-plated angle metal bars 34 which are suitably secured thereto and lap upon the outer sides of the walls 28, to which'they may be connected by bolts or other suitable fasteners 35, passing through the angle metal bars of the two top sections. The section 32 is also by preference tied to the top 8 of the burner containing casing, by bolts 36, and spacing lugs 37 may well be struck upwardly from said top, to prevent downward springing of the section 32, when the bolts 36 are tightened. The upper and lower edges of the top section 32 and the front edge of the section 31 are preferably equipped with nickel-plated finishing strips having rolled edges 38 which give a very attractive appearance to the heater. These finishing strips may be bolted or otherwise secured in place, as'will be readily understood.

Two vertically elongated members 39 are employed to close the spaces between the front edges of the two sets of side walls 5 ade of sheet metal as is also true of the entire jacket construction. The burner containing casing and base however may be of a cheaper grade of metal which does not have an attractive rtions of these walls in front The members 39 and the adjacent edges of the walls 5 and 28, are rearwardly spaced to some extent from the front flange 2 of the base 1, and secured to this flange, is a horizontal finishing strip 42 whose ends may well be bent-'rearwardly and inserted be tween the base and the side walls 28. Resting upon this finishing strip 42, is a horizontal sill plate 43 which is referably nickelplated and provided wit edge. A portion of. this sill plate extends rearwardly to the burner 10 and rests on the upper ends of the brackets 14, the latter forming supporting ledges for said plate, as will be clearly understood from Figs. 2 and 8. A suitable number of bolts or the like 44 9. rolled front pass through the base and the sill plate, to

secure the latter in place.

It will be seen from the foregoing, that while the casing is being heated b the burner and all unburned gases are ing consumed by said burner, an upward current of air will take place between the casing and the jacket, so that such current will be highly heated. The air enters the jacket near the floor and by taking the cold a1r from this location and effectively heating it, great efficiency is obtained.

As'excellent results have been obtained from the construction shown and described, it may well be followed. However, within the scope of the invention as claimed, numerous modifications maybe made.

I claim:
